Dick turned away; he continued his endeavours to pacify Dingo, and the conversation dropped.
The other thing that had arrested Dick's attention was the behaviour of the horse. If they had been as near the hacienda as Harris described, would not the animal have pricked up its ears, sniffed the air, and with dilated nostril, exhibited some sign of satisfaction, as being upon familiar ground?
But nothing of the kind was to be observed; the horse plodded along as unconcernedly as if a stable were as far away as ever.
Even Mrs. Weldon was not so engrossed with her child, but what she was fain to express her wonder at the deserted aspect of the country. No trace of a farm-labourer was anywhere to be seen! She cast her eye at Harris, who was in his usual place in front, and observing how he was looking first to the left, and then to the right, with the air of a man who was uncertain of his path, she asked herself whether it was possible their guide might have lost his way. She dared not entertain the idea, and averted her eyes, that she might not be harassed by his movements.
After crossing an open plain about a mile in width, the travellers once again entered the forest, which resumed something of the same denseness that had characterized it farther to the west. In the course of the afternoon, they came to a spot which was marked very distinctly by the vestiges of some enormous animals, which must have passed quite recently. As Dick looked carefully about him, he observed that the branches were all torn off or broken to a considerable height, and that the foot-tracks in the trampled grass were much too large to be those either of jaguars or panthers. Even if it were possible that the prints on the ground had been made by ais or other taidigrades, this would fail to account in the least for the trees being broken to such a height. Elephants alone were capable of working such destruction in the underwood, but elephants were unknown in America. Dick was puzzled, but controlled himself so that he would not apply to Harris for any enlightenment; his intuition made him aware that a man who had once tried to make him believe that giraffes were ostriches, would not hesitate a second time to impose upon his credulity.
More than ever was Dick becoming convinced that Harris was a traitor, and he was secretly prompted to tax him with his treachery. Still he was obliged to own that he could not assign any motive for the man acting in such a manner with the survivors of the "Pilgrim," and consequently hesitated before he actually condemned him for conduct so base and heartless. What could be done? he repeatedly asked himself. On board ship the boy captain might perchance have been able to devise some plan for the safety of those so strangely committed to his charge, but here on an unknown shore, he could only suffer from the burden of this responsibility the more, because he was so utterly powerless to act.
He made up his mind on one point. He determined not to alarm the poor anxious mother a moment before he was actually compelled. It was his carrying out this determination that explained why on subsequently arriving at a considerable stream, where he saw some huge heads, swollen muzzles, long tusks and unwieldy bodies rising from amidst the rank wet grass, he uttered no word and gave no gesture of surprise; but only too well he knew, at a glance, that he must be looking at a herd of hippopotamuses.

It was a weary march that day; a general feeling of depression spread involuntarily from one to another; hardly conscious to herself of her weariness, Mrs. Weldon was exhibiting manifest symptoms of lassitude; and it was only Dick's moral energy and sense of duty that kept him from succumbing to the prevailing dejection.
About four o'clock, Tom noticed something lying in the grass, and stooping down he picked up a kind of knife; it was of peculiar shape, being very wide and flat in the blade, while its handle, which was of ivory, was ornamented with a good deal of clumsy carving. He carried it at once to Dick, who, when he had scrutinized it, held it up to Harris, with the remark,-
